Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562044, here are decompositions:

11 + 31562033 = 31562044
71 + 31561973 = 31562044
197 + 31561847 = 31562044
233 + 31561811 = 31562044
263 + 31561781 = 31562044
347 + 31561697 = 31562044
383 + 31561661 = 31562044
401 + 31561643 = 31562044

Showing the first eight; more decompositions exist.
